FK-508 FG4 Rigid-Rail Guided Fall Arrester Trolley

The FK-508 FG4 is PGTEC's rigid-rail guided fall arrester trolley, certified to EN 353-1 and engineered to run inside an extruded aluminium I-beam safety track used as a permanent horizontal or vertical fall-protection rail on rooftops, gantries, maintenance walkways, crane booms and aircraft hangars. The trolley carriage is a compact navy-blue and silver block that sits inside the rail groove on low-friction stainless-steel rollers; it follows the worker freely as they walk along the rail, automatically locking in either direction the instant fall acceleration is detected, and caps peak arresting force below 6 kN. Because the rail is rigid there is no sag, no swing fall and no free drop, which is why rigid-rail systems are preferred on fragile-roof edges, glass skylights and overhead gantries where a flexible line would create dangerous pendulum hazards. The FG4 trolley connects to the harness dorsal D-ring through a short integrated lanyard and can be inserted or removed only at dedicated end stops, preventing accidental detachment. It is supplied as a trolley body that pairs with PGTEC's silver extruded aluminium rail, corner modules, floor and roof stand-offs, giving engineers a fully modular permanent fall-protection system. PGTEC backs the FG4 with a five-year warranty and a full range of rail accessories.
